BACKGROUND AND OBJECTIVES: Solid waste management which entails the generation, storage, collection, transportation, processing, treatment and disposal of waste products is regarded as a challenge to many countries worldwide. The focus and methods vary in all territories given the wide range of factors which influence waste management. Small Island Developing States face unique challenges which are influenced by their peculiar physical, economic, social, political and institutional characteristic. Consequently, they require a solid waste management system tailored to their unique requirements.METHODS: Qualitative and quantitative data were gathered between February and November 2019 from various primary and secondary sources using the following instruments and techniques: literature review of reports, news articles, legislation, journals and case studies; on-site observations; and administering questionnaires in the study area in October 2019. The study area comprised 3 communities which were representative of the waste management district, and were selected using the purposive sampling method, while the sample size of 0.3% of the households in the study area was selected randomly by administering questionnaires to anonymous respondents in arbitrary households in the communities. Using descriptive methods, data was tallied and grouped, then the content analysed to determine patterns, to answer questions to the problems and to determine relationships and themes. Findings were summarised, simplified and presented in formats such as graphs and tables and written descriptive accounts. FINDINGS: Solid waste management affects all countries irrespective of their level of development. The focal point varies across societies. Small Island Developing States have a unique challenge posed by their particular characteristics. Given that each territory has a peculiar mix of factors, any solid waste management system derived must be exclusive to each. There is no single, ideal system which can be proposed. Whatever the system decided upon, it must encompass the socioeconomic, cultural, economic, legislative, institutional and environmental context of the territory, but most of all it must be accepted by the majority of stakeholders. CONCLUSION: A solid waste management system must be unique to each area, given that there are many dynamic variables which affect the system. Consequently, the system derived from this study can only be applied in its entirety to the study area. Other areas with similar characteristics can lend examples from the study area.

In recent years managing solid wastes has been one of the burning problems in front of state and local municipal authorities. This is mainly due to scarcity of lands for landfill sites. In this context experts suggest that conversion of solid waste to energy and useful component is the best approach to reduce space and public health related problems. The entire process has to be managed by technologies that prevent pollution and protect the environment and at the same time minimize the cost through recovery of energy. Energy recovery in the form of electricity, heat and fuel from the waste using different technologies is possible through a variety of processes, including incineration, gasification, pyrolysis and anaerobic digestion. These processes are often grouped under “Waste to Energy technologies”. The objective of the study is twofold. First authors assessed the current status of solid waste management practices in India. Secondly the leading barriers are identified and Interpretive structural modeling technique and MICMAC analysis is performed to identify the contextual interrelationships between leading barriers influencing the solid waste to energy programs in the country. Finally the conclusions are drawn which will assist policy makers in designing sustainable waste management programs.
